First of all you need to understand that purpose of
grouping.
Group by is used when you need to club a few columns on the
basis of one column, for this you need to use some
aggregate functions,
for eg. for a table test
a b c
1 2 29-JUN-08
1 4 29-JUN-08
3 5 04-JUL-08
13 15 05-JUL-08
you can group a and b on c as follows:-
select count(a), max(b), c from test
group by c
count(a)max(b) c
2 4 29-JUN-08
1 5 04-JUL-08
1 15 05-JUL-08
